h指数与高被引文献指标相关性的实证研究

A Case Study of the Arbitrariness of the h-Index and the Highly-Cited-Publications Indicator

Michael Schreiber

摘要:

当需要q*h而不是h引用作为索引定义的阈值时,h索引的任意性变得明显,从而改变了数据集最有影响力的出版物的核心大小。我分析了26位物理学家的引用记录,以确定前因子q对排名的影响程度。同样,高被引出版物指标的任意性是由于阈值,要么作为引用的绝对数量,要么作为高被引论文的百分比。对26条引文记录的分析表明,依赖于这些阈值的排名变化相当大,与h指数的相应变化相当。

英文摘要:

The arbitrariness of the h-index becomes evident, when one requires q*h instead of h citations as the threshold for the definition of the index, thus changing the size of the core of the most influential publications of a dataset. I analyze the citation records of 26 physicists in order to determine how much the prefactor q influences the ranking. Likewise, the arbitrariness of the highly-cited-publications indicator is due to the threshold value, given either as an absolute number of citations or as a percentage of highly cited papers. The analysis of the 26 citation records shows that the changes in the rankings in dependence on these thresholds are rather large and comparable with the respective changes for the h-index.
